[aspectj-users] RE: load weaving EJB
|
Thanks for replying Dean Wampler,
As he said that I have to do load weaving with my EJB container. How can I
do that?

Actually, it would print
Hi Toy My Surname
Hi Toy
If you run this code as a normal Java application (replacing the
InitialContext stuff with "new MyBean()", for example), it works fine.
First, did you compile the code with ajc? If not, are you using load-
time weaving with your EJB container?
I haven't used EJBs in a long time, so I'm not sure how this code is
really implemented and managed by the container. However, I suspect
that you aren't getting an object of type MyBean, but some proxied
object or even a subclass (like they used to do in EJB v2).
Try adding a plus sign, "+" in your pointcut definition:
pointcut insertSurname() : execution(public String MyBean
+.sayHello(..));
This tells AspectJ to match on subclasses too. That might work. If
not, perhaps someone else on the list will have the answer.
Good luck,
Dean
